Inventor: SUGITA NARUTOSHI
IPC: H01M8/24
Filed: 2000-08-22
Abstract: A fuel cell system comprises first and second fuel cell stacks in which directions of a positive electrode and a negative electrode of adjoining terminal electrodes are set to be opposite to one another. First and second conductive plates are incorporated at ends on an identical side of the first and second fuel cell stacks. First and second connecting plate sections are provided to extend from the first and second conductive plates closely to one another under the first and second fuel cell stacks. The first and second connecting plate sections are electrically connected by strand wires having flexibility. Accordingly, it is possible to reliably avoid any action of stress which would be otherwise caused by vibration or the like at a connecting portion for electrically connecting the first and second fuel cell stacks to one another which are arranged in parallel to one another.

Title: Method and apparatus for measuring the calorific value of a gas
Inventor: HAMMOND PAUL STEVEN
IPC: G01K11/24
Filed: 1999-01-08
Abstract: Apparatus (2) comprises a chamber (4) to which a gas in question, for example natural gas is supplied through inlet (6) and leaves through outlet (8). The speed of sound SoS at ambient temperature is measured using any suitable method such as electronic control and calculating means (14) and an ultra-sound emitter (10) and an ultra-sound receiver (12). The ambient temperatures Ta is observed by temperature sensor (22), and a thermal conductivity sensor measures the thermal conductivity of the gas at two different temperatures above ambient temperature. One value ThCH of the thermal conductivity is measured at 70 ~C above ambient and the other value ThCL of the thermal conductivity is measured at 50 ~C above ambient. The control means (14) calculates the calorific value CV of the gas according to the formula: CV =  a.ThCH + b.ThCL + c.SoS + d.Ta + e.Ta2 + f. where a, b, c, d, e and f are constants.

IPC: H04B10/07
Filed: 1999-03-08
Abstract: Pour fabriquer des modules électro-optiques (1), au moins un module d'émission optique et au moins un module de réception optique sont fabriqués sur le même substrat. Des guides d'ondes optiques (9) sont disposés sur le substrat entre un composant (7) émetteur de lumière situé dans un module et un composant (15) détecteur de lumière situé dans un module voisin. Le composant émetteur de lumière et le composant détecteur de lumière sont excités et la transmission de la lumière entre les composants est testée. Ensuite, le substrat est divisé en modules individuels le long de lignes de division (3). La connexion optique entre les modules est alors rompue et les guides d'ondes peuvent être connectés à des fibres optiques à l'aide d'un connecteur. Des circuits d'attaque (11, 17) électroniques peuvent être montés sur les modules. Les modules peuvent également posséder des connexions électriques intégrées entre les circuits d'attaque et les composants optiques. De cette manière, l'essai optique est effectué de manière simple et automatique et n'exige qu'un minimum d'opérations manuelles, étant donné que tous les modules émetteurs et récepteurs peuvent être testés en même temps dans le même équipement d'essai.

Title: Apparatus for evaluation of skin impedance variations
Inventor: SZOPINKSI JAN ZBIGNIEW
IPC: A61B/
Filed: 1999-07-06
Abstract: The invention provides an apparatus and method for automatic evaluation of skin resistance or impedance variations in order to diagnose the state of health of at least a portion of a human or animal body, The difference between an AC impedance measured at a specific frequency and at a specific skin area with a calibration electrode and a reference electrode and the impedance measured at a similar frequency and in the same area with a measurement electrode and a reference electrode, is used to determine the state of health of the internal organ corresponding to the examined skin area. Alternatively, the skin between the electrodes is exposed to a DC potential of a magnitude selected to give a break-through effect. The resistance of the skin is measured between a measurement electrode polarised negatively with respect to a reference electrode, and the DC resistance of the same skin area is again measured but with the measurement electrode polarised positively with respect to the reference electrode. The ratio of these two values is used to determine the state of health of the internal organ corresponding with the examined skin area.

Abstract: A method of demodulation and equalization is used to process an amplitude modulated compatible digital broadcasting signal including an amplitude modulated radio frequency signal having a first carrier modulated by an analog program signal in a first frequency spectrum, a plurality of digitally modulated carrier signals positioned within a bandwidth which encompasses the first frequency spectrum, a first group of the digitally modulated carrier signals including complementary carrier signals and lying within the first frequency spectrum, and second and third groups of the digitally modulated carrier signals including non-complementary carrier signals and lying outside of the first frequency spectrum. The method includes the steps of: taking a first Fast Fourier Transform of the amplitude modulated compatible digital signal to produce a first transformed signal representative of the non-complementary carriers; processing the first transformed signal to produce a first equalized signal by multiplying the first transformed signal by a first equalization vector, wherein the first equalization vector includes a first plurality of equalizer coefficients;  updating the first plurality of equalizer coefficients; taking a second Fast Fourier Transform of the amplitude modulated compatible digital signal to produce a second transformed signal representative of the complementary carriers; determining a second equalization vector comprising a second plurality of equalizer coefficients, wherein the second plurality of equalizer coefficients is determined by interpolating coefficients of the first plurality of equalizer coefficients; and processing the second transformed signal to produce a second equalized signal by multiplying the second transformed signal by the second equalization vector. The invention also encompasses the operation of radio frequency receivers which utilize the. above method, as well as apparatus that performs the above method and radio frequency receivers which utilize the above equalization method.

Title: A predictive image caching algorithm
Inventor: SKOLL DAVID F
IPC: G06T1/60
Filed: 2001-05-29
Abstract: Methods of caching tile image constituents of image-mosaics enable a substantially smooth real-time display of portions of the image-mosaic in a view during panning, re-sizing, or zooming of the view. The method includes using a predictive algorithm to identify tile images to be retrieved from a remote store through a local area network, and for sequencing requests for the retrieval of tile images from the remote store. A scheduler calculates time spent in retrieving and servicing each tile image retrieval request and proportionately pauses retrieval of tile images after each request is serviced in order to prevent over utilizing LAN resources. The advantages are that tile images to be displayed are cached in accordance with a priority to facilitate image display while network data transfers are distributed in time.
